Entering a locked GS via the Smart Access system is
as easy as touching the inside of any door handle or the
underside of the trunk lid, as long as you've got the key
fob on your person. First seen on the
LS430, this is a worthwhile convenience
and also saves door paint from wayward keys seeking small
keyholes. Once seated, the driver starts and stops the engine
by simply applying the brake pedal and pushing a stop /
start button. Again, the convenience is augmented by practical
considerations: fewer moving parts to require potential
repair, and the elimination of a safety risk posed by a
bunch of sharp-edged keys dangling from the console. Smart
Access also allows the key fob to be programmed to memorize
three different settings for the front seats, steering column,
and rearview mirrors.
The 10-way adjustable seats and electronically adjustable
steering column ensure a good fit for almost every physique,
but a bit more bolstering and a longer seat cushion would
be helpful for spirited driving. The GS is capable of extraordinary
road grip, but the seats just don't quite match up to that
grip. Otherwise, they're just the kind of chairs that allow
you to climb out after a long drive without needing your
spine cracked. Adjustable headrests are found at all five
seating positions, and the fronts automatically adjust up
or down as the seats are moved toward or away from the steering
wheel.
Push that start button yet? Better check by blipping
the throttle, because there's no way you're going to hear
the engine, V6 or V8, at idle. All GS models are extraordinarily
quiet, their aural distinctions to be appreciated only at
full throttle. It's then that the V8 separates itself from
its new, smaller sibling. The big engine
scarcely notices the weight it must pull or the air it must
push, and the suck, squish, bang, and blow of the eight
cylinders is reduced to a muted rumble from the dual exhaust
system.
Throw in a six-speed automatic that is so smooth
as to seem one continuous gear, and there's little to do
except sit back and enjoy the ride. At its most fuel deficient,
the GS430 jets from 0 to 60 mph in just 5.7 seconds, with
the driver's chief sensation simply the rapid change of
view outside the windows. A bit of road noise manages to
make it through the sound-dampening measures, and there's
a hint of wind around the A-pillars when the car approaches
triple digits, but otherwise the cockpit is a librarian's
paradise.
Handling is virtually no-fault. The newly engineered
suspension is state of the art even without all the electronic
handling aids. Both V6 and V8 cars share the same suspension
geometry: double-wishbones, coil springs, and gas-filled
shocks in front, and a multi-link design with coil springs
and gas-filled shocks out back. The GS430 also features
standard Adaptive Variable Suspension, which automatically
adjusts shock values depending on the driving conditions,
or the driver can choose between normal and sport modes.
But, is it an exciting car to drive? If your only measure
of driving fun is speed, then the 430 is a fulfilling ride.
But, if you value a high level of feedback from external
forces, then the Lexus experience might be a bit of a bore.
It is just so competent and smooth that the driver feels
more like a passenger than the commander. Make no mistake;
this is no track car. The electronic handling aids cannot
be switched off, so tail-happy cornering is out of the question.
However, there's a lot to be said for the ease of taking
a corner at competitive speeds without having to wrestle
the steering wheel or worry about the rear end overtaking
the front.
Driving fans should consider the rear-drive GS300. In
comparison to the outgoing inline six-cylinder engine, the
new V6 produces more torque over a wider range, better fuel
economy, and lower emissions, and it produces some very
pleasing
sounds as it goes about its business. Featuring such advanced
aspects as drive-by- wire throttle, variable adjustment
of the timing on both the intake and exhaust sides, direct-to-cylinder
injection, and a special Swirl Control Valve that works
like a variable induction system, the V6's 245 horsepower
can take the GS 300 to 60 mph in 6.8 seconds.
The V6 is not an effortless puller like the V8, but
it's no slouch, either. The generous torque provides plenty
of juice for the stoplight grand prix, and there's little
sense of the power falling off as redline is approached.
Better still, the V6 provides the kind of aural feedback
that delights the sporting driver.
Whichever drivetrain is chosen, the GS has pretty much
hit its targets. In those areas most critical to driving
fun (steering, brakes, and torque) this is a far better
car than its predecessor. A lot of attention was paid to
the steering, resulting in a new Electronic Power Steering
system. A steering ECU processes vehicle speed, yaw rate,
and steering angle to determine how much electronic assist
should be
generated, and it works wonderfully well, assisting low-speed
maneuverability and tightening up when more feedback is
needed.
In addition, the GS430's rack is augmented by Variable Gear
Ratio Steering (VGRS), which reduces the amount of steering
input at very low speeds. It also accelerates the steering
angles as the wheel approaches full lock. VGRS itself incorporates
Differential Steering Control and Correction Steering Angle
Reduction in its operation. DSC closely matches wheel angle
to the speed at which the driver is turning the steering
wheel in order to offset any delay in the car's response
to steering input. This works especially well on winding
roads. CSAR features a correction feature to offset the
effects of sidewinds, making the steering adjustments normally
having to be done by the driver.

This might sound too much like Big Brother taking over
the wheel, but none of these systems are intrusive and do
little to diminish the performance aspects of the new GS.
This car comes in three flavors, all of them delectable,
but all of them a variation of vanilla. Don't get us wrong;
we like vanilla. But, when we were told the GS would make
us forget about the BMW driving experience, it had our taste
buds flipping into overdrive and hungry for a spicier kind
of road cuisine than we'd come to expect from Lexus. We're
still waiting.
